Hey Hive committers - can one of you please take a look at this patch? We'd love to let users
start using sets!

> Thrift supports a type "set" which maps to "java.util.Set". Hive should support this
as well.
> We can either add "set" to "array", "struct", "map", or we can just treat "set" as an
"array" which will be easier to do.
> This is blocking Hive from doing "SELECT *" on some tables defined by thrift, because
thrift supports "set" right now.
